You can use some softwares (such as ENVI) to perform the spectral unmixing, then the endmembers and their corresponding abundance matrices can be obtained.

Thank you Mr. Firoz Mahmud and Lingxiao, I got some idea by Mr Firoz mahmud provided URL. There is some CPP code to find enmembers. I'll try that, thank you very much for both of you.

First extract end members for your input image.. From the end members by applying techniques like fully constrained least square estimation we can generate abundance maps and matrices..
